摘要
沁水盆地煤层气井已进入大规模开发阶段,目前主要问题是许多煤层气井产量低,且低产井所占比例较高。本文通过与实际煤层气井显示的表象进行对比,初步揭示了煤层气井低产的主要原因,并根据不同气井的产水量给出了相应的具体解决措施,为这些低产井的排水采气提供了指导性意见和建议。提出了深入研究煤层气储层中水的区域分布对煤层气开发的重要性。
The CBM wells in Qinshui basin have entered the stage of large scale development. Current- ly, the major problem is low yield for most CBM wells, which constitute a great proportion of the existing wells in the basin. Based on water production of different CBM wells, the paper proposes concrete meas- ures for corresponding cases, which provide of low yield wells. The paper points out the bution of water in CBM reservoir guiding opinions and suggestions for dewatering and drainage importance of further to-the-depth research on regional distri-
